A flow path is formed in an intake port (3a) provided in a central part in the axial direction of the first housing (3) and a blowing passage (8a) connecting the intake port (3a) and the discharge port (8b) as top surface portions (3e1, 2c1) of a housing-side shroud (3e) connecting to the intake port (3a) and an impeller-side shroud (2c) formed in the impeller (2) which face the blowing passage (8a) are adjacent to each other in the radial direction.
